Abstract
A display device includes a display panel, a light guide plate, a first light source unit, and an optical member. The light guide plate is on the display panel. The first light source unit is configured to provide light to a side surface of the light guide plate. The optical member is between the light guide plate and the display panel. The optical member includes an interconnection layer, an optical pattern unit including first optical patterns on a surface of the interconnection layer, and first pattern shaping wires configured to receive a control voltage from the interconnection layer and to control a shape of each of the first optical patterns via the control voltage. Each of the first optical patterns is connected to a respective some of the first pattern shaping wires.
